' si-IEET-rnINTING a citizen ofthe United Sta`tes,`l residing at l-Nevv York', county of Kingsfand State of Neiv'York, have invented certain new .and

' useful Improvements lin Sheet-Printing 'Machines, fully described and represented .in fthe Vfollowing specification Vand the accom- `panying drawings, forming` a part 0I" the same. v

. This invention relatesto certain improvements in sheetfprinting 1nachines.'

l In` printing sheets Whichare 'to 'receive' more than' one impression it is usual "to deliver the 'sheet after each" impression, the sheetsbeing piled, The sheets from thispile aref then again run through another orthe same machine to receivean additional impression. 'I his requiresadditional handling.

of the sheets andthere is, further, 'liability of offsetting unless the practice of using slip lsheets is resorted to.

The l'present invention has for Vits object to produce an improved printing machine ffor printingon sheets by Whichthe piling and additional handling of the sheetsbetweenimpressions is avoided,A the machine' embodying a singlev printing couple and means vfory automatically successively .pre-

senting sheets todi'erent parts of the couple to receive successive impressions.' Q A Withzthis and other objects not specifically referred to in View, the -invention consists in certain constructions and in certainV parts,l improvements and combinations as will be hereinafter described. and then' specifically pointed out.

Referringfto the drawin ls:--I" `igure -`1 is aplan View of' 'somucho aprmting'machine constructed in accordance with the inv`l i vention as is'necessary to 'an understanding thereof. A Figi` 2 is a 'side elevation of -the construction s hovvn inlFig. 1. 'Fim 3 isa.

,advanced pers of the cylinder open and the sheet is I delivered onto the rollers 13 on the frame 12, the delivery being assisted by a propeller roll 2l and a stripper or guide 22. The sheet will, therefore, be given a sidewise travel by the rollers and at the same time toward the front guides, this being due to the diagonal arrangement. of the by, a receiving mechanism for taking the sheet after printing, and means, out of the entering sheet path, including a transferring mechanism and a suitable registering guide for delivering the sheet to another part of the couple to receive another printing.

4. The combination'with a rotary multiple Wide printing couple, of means constituting an entering sheet path for presenting a sheet to one part of the couple to be printed thereby, a. rotary sheet receiving mechanism for taking the sheet after printing, and means out of the entering sheet path and coperating with the receiving mechanism for again delivering the sheet to the couple to receive another printing.

5. The combination with a rotary multiple wide printing couple, of means constituting an entering ,sheet path and including suitable front stops for presenting a sheet to one part of the couple te be printed thereby, a rotary sheet receiving mechanism for taking the sheet after printing, and means out of the entering sheet path and includrollers. Suitable means, such as a guide, should be provided for determining the amount of sideWise travel of the sheet, so that it may be brought into proper register to be again delivered to the printing couple. ln the construction shown, a side guide 23 is provided for this purpose.

In machines embod ing the invention in its best form, a suitable stop will be provided so as to prevent the sheet from coining .against the front stops 6 before the stops are positioned to receive them. lVhile the stop may be of anysuitable character, in the particular construction shown, a rock shaft 24 carrying stop lingers 25 is provided for this purpose. This shaft 24 Will be rocked at any desired time by suitable coni nections from the machine. I

for presenting the sheet to another part of the couple to receive another printing.

6. The combination With a rotary multiple wide printing couple, of means constivtilting an entering sheet path and including suitable sheet stops for presenting a sheet thereto to receive a printing therefrom, a rotary sheet receiving mechanism for taklng the sheet after printing, a transferrer located out of the entering sheet path and embodying diagonally arranged rollers, and means for registering the sheet sidewlse, whereby the sheet maybe again presented to the printing couple to receive another printing therefrom. Y

7. The combination with a rotary multiple wide printing couple, of means for presenting a sheet to one end thereof t -o be printed thereby, a pair of sheet recelvlng cylinders for taking the sheet, a set of diagonally arranged transferring rolls to take Changes and variations may be made in the construction by which the invention is carried into effect. The invention claimed, therefore, is not to be confined to the par ticular construction herein shown and described.

1Viv/That is claimed is:-

l. The combination with a multiple wide printing couple, of means constituting an entering sheet path for presenting a sheet to one part of the couple to be printed there` by, means for receiving the sheet from said part and turning it, and means out of the entering sheet path for taking the sheet from said receiving means and simultane` ously moving said sheet laterally and forward for presentation to the next part of the printing couple.

2. The combination with a multiple wide printing couple, of means constituting an entering sheet path for presenting a sheet part of the couple to be printed thereby, a receiving mechanism for taking the sheet after printing, and means coperatin with the receiving mechanism and out o the enterin'g sheet path for delivering the sheet to another part of the couple to receive another printing.

3. The combination with a multiple wide printing couple, of means constituting an entering sheet path for presenting a sheet to one part of the couple to be printed therei to one it sidewise and present 1t to the couple to receive another tering devices. A
